FWIW, I also run an Aimpoint CompML2 and I prefer the new XPS series Eotechs. My suggestion to the OP or anyone else is to arrange to mount both to a rifle, look through them at both light and dark corners of the shop, ideally at a distance of 15m or further away and decide which is more comfortable for you. Even better if you can do a shooting trial.
Not everyone's eyes reacts the same to HWS and red-dots. Ergonomically not everyone will like the same rifle balance between the various options out there.
Frankly, I think you can't go wrong with an XPS, EXPS or most of the aimpoint lineup for a CQB-type sight. They are all light (enough) and durable (enough) for any range use on a 5.56 firearm.
